class_docstr: Interface for receiving logical document content events.
  
  This is the main callback interface in SAX, and the one most
  important to applications. The order of events in this interface
  mirrors the order of the information in the document.
docstr: Signals the start of an element in non-namespace mode.
  
  The name parameter contains the raw XML 1.0 name of the
  element type as a string and the attrs parameter holds an
  instance of the Attributes class containing the attributes of
  the element.
